DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the drawings and the illustrative embodiments depicted therein, an exterior rearview mirror assembly 10 for a vehicle 11 includes a mirror reflective element 12 received in and/or supported at or by a mirror shell or casing or head portion 14 (FIG. 1). The mirror casing or head portion 14 may be fixedly attached at a mounting arm or base 16 at the side of the vehicle or may be movably mounted to a mounting arm or base or portion 16, and may comprise a breakaway mirror (where the mirror head portion may be manually pivoted about the mounting arm or base) or may comprise a powerfold mirror (where the mirror head portion may be pivoted via an actuator assembly or adjustment device). Mounting arm or base 16 of mirror assembly 10 is mounted at the side 11 a of a host or subject vehicle 11, with the reflective element 12 providing a rearward field of view along the respective side of the vehicle to the driver of the vehicle, as discussed below.

As shown in FIGS. 2-4, the mirror assembly comprises a powerfold mirror assembly that includes an actuator 18 that is operable to pivot the mirror head 20 (comprising the mirror casing 14 and reflective element 12) relative to the mounting arm or base 16. The actuator operates, response to a user input 22 (FIG. 6A), to pivot the mirror head 20 between a plurality of detent positions, including a forward position (FIG. 2), a user or drive position (first position in FIG. 5A) and a folded or park position (second position in FIG. 5A). Optionally, the mirror head may also be pivoted to a fully forward detent position (second position in FIG. 5B).

Known powerfold detent systems can be confusing to end users. For example, the mirror head may appear as if it is at the drive or home position but it could be out of the detent position, which may result in warranty returns due to the corresponding poor vibration performance and because the mirror head may feel like it is broken or loose. After a manual adjustment or cycle of the mirror head, a known powerfold mirror system may need multiple button presses to get the mirror head to the desired position or positions. There is no positional feedback in current or known powerfold systems. A current exemplary powerfold system allows the mirror to stop at thirteen different states after different combinations of power folds and manual fold cycles. Today there is no positional feedback in the mirror and because of that it can take multiple (such as up to three) cycles of the user's powerfold actuator button to return the mirror to the drive position. For example, when the mirror is pivoted forward (such as shown in FIG. 2), such a mirror state may require three cycles of the user's powerfold input or button to return the mirror to its drive position (see, for example, FIG. 5B). Likewise, and such as shown in FIG. 5A, it may take two actuations of the user's powerfold input or button to move the mirror head from its drive or use position to the forward pivoted state (because the first actuation pivots the mirror head to its park or folded position or state).

The mirror assembly of the present invention includes one or more sensors in the mirror to reduce the number of user inputs to only one input or actuation for all scenarios or positions of the mirror head. The present invention thus may add positional feedback and “intelligence” into the mirror system in order to correctly move the mirror with minimal assumptions and minimal inputs from the driver. The present invention may include a built in shut off device that monitors both voltage and temperature of the powerfold actuator. The powerfold system or systems of the present invention may be operable in response to a single button powerfold user input (see user input 22 in FIG. 6A), whereby the powerfold actuator alternates the rotation direction on every switch actuation (for example, if a first actuation of the powerfold user input pivots the mirror head in a direction towards the folded or park position, the next actuation of the user input will pivot the mirror head in the opposite direction or towards the forward position), or may be operable in response to a two button powerfold user input (see user input 23 in FIG. 6B), whereby the powerfold actuator rotates in the direction that is indicated on each of the buttons on the switch or user input.

The powerfold system of the present invention includes one or more sensors to assist the system in knowing the position or general position of the mirror head so that the mirror head is adjusted appropriately in response to the user input or inputs. For example, and with reference to FIG. 7, the powerfold system may include a detent sensor 24 at the actuator 18. The detent sensor may comprise any suitable sensor, such as a mechanical switch or hall effect switch or the like, that detects if the mirror head is lifted and is out of one of the detents of the mirror assembly.

Optionally, and with reference to FIG. 8, the powerfold system may include a friction device 26 at the actuator 18. The friction device may comprise any suitable device, such as a mechanical device that holds the location of the pivot arm and mirror head relative to the base when the mirror head is lifted out of the detent or detents. The friction device limits pivotal movement of the mirror head in such situations, but will still allow the mirror head to be rotated by a manual outside force at the mirror head.

When the powerfold mirror is manually adjusted (such as may occur via manual movement of the mirror head by a person manually pivoting the mirror head out of a detent position or by an impact at the mirror head, such as by the mirror head contacting or impacting an object, such as during movement of the vehicle or during movement of an object relative to the vehicle and mirror head, where such contact or impact moves or pivots the mirror head out of a detent position), the detents become disengaged. Assuming the next function after manual adjustment is electrical adjustment, the powerfold mirror and actuator may either (i) re-engage the detents without moving the mirror head or (ii) move the mirror head without immediately re-engaging the detents. In the second case, the detents would eventually re-engage after the mirror head reaches a physical stop (where the mirror head no longer moves). Typically, either of the two scenarios can occur depending on how much friction there is at the different slipping interfaces.

The friction device of the present invention causes the detents to re-engage before the mirror head moves. This is accomplished by adding more friction to the slip interface between the mirror head/arm and the base/rivet tube. The friction device may increase the friction only when a manual adjustment occurs.

Optionally, and with reference to FIGS. 9A and 9B, the powerfold system may include a rearward range sensor 28 at the actuator 18. The rearward range sensor may comprise any suitable sensor, such as a sensor that detects if the mirror head is anywhere rearward of drive position (towards the park or folded position). For example, the rearward range sensor may comprise a hall effect sensor that is mounted at the base and an arc-shaped magnet that is mounted at the arm. When the mirror head is at a rearward position, the sensor may detect the presence of the magnet at or near the sensor, whereas when the mirror head is pivoted to the drive position or forward of the drive position, the magnet is moved away from the sensor and the sensor does not detect its presence. Optionally, and as shown in FIGS. 9A and 9B, the sensor 28 and magnet may be mounted at the base and a steel stamping 29 may be mounted at the arm so that, when the mirror rotates, the stamping travels between the magnet and the sensor.

Optionally, and with reference to FIGS. 10A and 10B, the powerfold system may include a drive position sensor 30 at the actuator 18. The drive position sensor may comprise any suitable sensor, such as mechanical switch or hall effect sensor or switch (such as a sensor disposed at a circuit board of the actuator or mirror assembly) that detects when the mirror head is at the drive detent position. When the mirror head is at the drive position, the sensor detects a magnet that is disposed at the arm or mirror head and that is near the sensor when the mirror head is at the drive position and remote from the sensor when the mirror head is not at the drive position.

According to one aspect of the powerfold system of the present invention, the mirror assembly may include a detent sensor 24 and a single powerfold user input or button 22 (disposed in the vehicle and actuatable by a driver of the vehicle when the driver is normally operating the vehicle). Every time the powerfold button is pressed and the mirror head is out of one of the detent positions (as determined by the detent sensor), the mirror head will rotate to the park position to reset the actuator and then go to drive position. This includes when the mirror head is at a forward and out of detent position or between the park and drive detent positions. Thus, if the mirror head is between the park and drive positions and out of detent, the mirror head will move to the park position and then move back towards and to the drive position. Otherwise, the powerfold mirror will function the same as known powerfold mirrors.

Such a powerfold system provides a reduced cost and relatively simple system, which also provides for movement of the mirror head without delay when the user input or button is actuated. The powerfold system makes the assumption that the user wants the mirror to return to the drive position when the mirror head is out of the detent positions (but could instead move or adjust the mirror head towards the park position when the mirror head is out of the detent positions). With this powerfold system of the present invention, the user input may still need to be pressed multiple times to move the mirror head from a “forward in detent” position to the drive detent position. It is envisioned that the system will include communication between the driver and passenger side mirrors so that the mirror heads can stay in sync and are at the same relative positions.

According to another aspect of the powerfold system of the present invention, the mirror assembly may include a detent sensor 24 and a rearward range sensor 28 and a friction device 26 and a single powerfold user input or button 22. In this application, every time the powerfold button is pressed and the mirror head is out of the detent positions (such as may occur via manual movement of the mirror head, such as by a person manually pivoting the mirror head out of a detent position or by an impact at the mirror head, such as by the mirror head contacting or impacting an object, such as during movement of the vehicle or during movement of an object relative to the vehicle and mirror head, so as to move or pivot the mirror head out of a detent position), the actuator will reset the detent without moving the mirror head. Before moving the mirror head, the system will sense if the mirror head is either anywhere rearward of the drive position or in the drive position or forward of the drive position. Depending on the determined mirror head position, the system will take various actions. For example, if the system determines that the mirror head is rearward of the drive position, the actuator will pivot or adjust the mirror head to the drive position, and if the system determines that the mirror head is at the drive position or forward of the drive position, the actuator will pivot or adjust the mirror head to the park position.

Thus, this powerfold system of the present invention may perform as a “one button press” solution for all user scenarios. It is envisioned that the system will include communication between the driver and passenger side mirrors so that the mirror heads can stay in sync and are at the same relative positions.

According to another aspect of the powerfold system of the present invention, the mirror assembly may include a detent sensor 24 and a drive position sensor 30 and a friction device 26 and a single powerfold user input or button 22. In this application, every time the powerfold button is pressed and the mirror head is out of the detent positions, the actuator will reset the detent without moving the mirror head. When the powerfold button is pressed, the actuator will start to move the mirror towards the park position and depending on the scenario the mirror will end up in the drive position or in the park position. For example, when the mirror head is at the drive position (as determined by the drive position sensor), the drive position sensor will be active and the mirror head will rotate to the park position, and when the mirror head is at the park position, the mirror head will rotate towards park and there will be an instant current spike and the mirror will rotate to the drive position. When the mirror head is at a forward position, the mirror head will rotate towards park and the drive position sensor will trigger during the move and when the drive position sensor turns off, the actuator will then reverse its direction and rotate the mirror head back to the drive position. When the mirror head is between the park and drive positions, the mirror head will pivot towards the park position and the current will spike before the drive position sensor is triggered, whereby the mirror may either stay at the park position or go back to the drive position (depending on the particular application and customer preferences of the powerfold system and exterior rearview mirror assembly).

Thus, this powerfold system of the present invention may perform as a “one button press” solution for all user scenarios. Also, this system has a less complex, lower cost, point position sensor compared to the range sensor. It is envisioned that the system will include communication between the driver and passenger side mirrors so that the mirror heads can stay in sync and are at the same relative positions.

According to another aspect of the powerfold system of the present invention, the mirror assembly may include a detent sensor 24 and a drive position sensor 30 and a rearward range sensor 28 and a friction device 26 and a single powerfold user input or button 22. In this application, every time the user input or PF button is pressed and the mirror head is out of the detent positions (such as may occur via manual movement of the mirror head, such as by a person manually pivoting the mirror head out of a detent position or by an impact at the mirror head, such as by the mirror head contacting or impacting an object, such as during movement of the vehicle or during movement of an object relative to the vehicle and mirror head, so as to move or pivot the mirror head out of a detent position), the actuator will reset the detent without moving the mirror head. When the powerfold button is pressed, the system will sense the mirror head location using the three position sensors and will respond accordingly. For example, when the user input is actuated when mirror head is at the drive position, the drive position sensor will be active and the mirror head will rotate to the park position. When the user input is actuated when the mirror head is at the park position, the rearward range sensor will be active and the mirror will rotate to the drive position. When the user input is actuated when the mirror head is at a forward position, neither the drive position sensor nor the rearward range sensor would be active, so the actuator would rotate the mirror head rearward until the rearward range sensor is active and then it would reverse its direction to move the mirror head at the drive position. When the user input is actuated when the mirror head is at a position between the park and drive positions, the rearward range sensor will be active and the actuator will rotate the mirror head to the drive position.

Thus, this powerfold system of the present invention may perform as a “one button press” solution for all user scenarios. Also, this system has a less complex, lower cost, point position sensor compared to the range sensor. It is envisioned that the system will include communication between the driver and passenger side mirrors so that the mirror heads can stay in sync and are at the same relative positions.

According to another aspect of the powerfold system of the present invention, the mirror assembly may include a detent sensor 24 and a drive position sensor 30 and a friction device 26 and two powerfold user inputs or buttons 23. In this application, every time the powerfold button is pressed and the mirror head is out of the detent positions, the actuator will reset the detent without moving the mirror head. When the “MOVE TO DRIVE” powerfold button is pressed, the actuator will start to move the mirror head towards the park position and will complete the movement depending on the particular scenario. For example, when the “move to drive” user input is actuated when the mirror head is at the drive position, the drive position sensor will be active and the actuator will not move the mirror head. When the “move to drive” user input is actuated when the mirror head is at the park position, the actuator will pivot or move the mirror head towards the park position and there will be a current spike and the mirror will rotate to the drive position. When the “move to drive” user input is actuated when the mirror head is at a forward position, the actuator will pivot or move the mirror head towards the park position and the drive position sensor will trigger during the move and when the drive position sensor turns off, the actuator will then reverse its direction and rotate the mirror head back to the drive position. When the “move to drive” user input is actuated when the mirror head is between the park and drive positions, the actuator will move the mirror head towards the park position and the current will spike before the drive position sensor is triggered and the actuator will move the mirror head to the drive position.

Similarly, when the “MOVE TO PARK” powerfold button is pressed, the actuator will start to move the mirror towards the park position and will complete the movement depending on the particular scenario. For example, when the “move to park” user input is actuated when the mirror head is at the drive position, the actuator will rotate the mirror head towards the park position until the motor stalls. When the “move to park” user input is actuated when the mirror head is at the park position, the actuator will rotate the mirror head towards the park position until motor stalls. When the “move to park” user input is actuated when the mirror head is at a forward position, the actuator will rotate the mirror head towards the park position until motor stalls. When the “move to park” user input is actuated when the mirror head is between the park and drive positions, the actuator will rotate the mirror head towards the park position until motor stalls.

Thus, this powerfold system of the present invention may perform as a “one button press” (of the selected button for the desired final position of the mirror head) solution for all user scenarios. Also, this system has a less complex, lower cost, point position sensor compared to the range sensor. Another benefit of this system is that the driver side and passenger side mirrors will automatically sync together.

According to another aspect of the powerfold system of the present invention, the mirror assembly may include a detent sensor 24 and a rearward range sensor 28 and a friction device 26 and two powerfold user inputs or buttons 23. In this application, every time the powerfold button is pressed and the mirror head is out of the detent positions, the actuator will reset the detent without moving the mirror head. When the “MOVE TO DRIVE” powerfold button is pressed, the actuator will move the mirror head depending on the particular scenario. For example, when the “move to drive” user input is actuated when the mirror head is at the drive position, the rearward range sensor will not be active so the actuator will rotate the mirror head towards the park position until the rearward range sensor is active and then will rotate the mirror head back to the drive position. When the “move to drive” user input is actuated when the mirror head is at the park position, the rearward range sensor will be active so the actuator will pivot or move the mirror head towards the drive position. When the “move to drive” user input is actuated when the mirror head is at a forward position, the rearward range sensor will not be active so the actuator will rotate the mirror head towards park just until the rearward range sensor is active and then rotate the mirror head back to the drive position. When the “move to drive” user input is actuated when the mirror head is between the park and drive positions, the rearward range sensor will be active and the actuator will move the mirror head to the drive position.

Similarly, when the “MOVE TO PARK” powerfold button is pressed, the actuator will start to move the mirror towards the park position and will complete the movement depending on the particular scenario. For example, when the “move to park” user input is actuated when the mirror head is at the drive position, the actuator will rotate the mirror head towards the park position until the motor stalls. When the “move to park” user input is actuated when the mirror head is at the park position, the actuator will rotate the mirror head towards the park position until motor stalls. When the “move to park” user input is actuated when the mirror head is at a forward position, the actuator will rotate the mirror head towards the park position until motor stalls. When the “move to park” user input is actuated when the mirror head is between the park and drive positions, the actuator will rotate the mirror head towards the park position until motor stalls.

Thus, this powerfold system of the present invention may perform as a “one button press” (of the selected button for the desired final position of the mirror head) solution for all user scenarios. Another benefit of this system is that the driver side and passenger side mirrors will automatically sync together.

Thus, the powerfold systems of the present invention provide various means for adjusting the mirror head to the park position or drive position. The chart of FIG. 11 shows the various elements of each system and the adjustments made by the system responsive to the user input and initial position of the mirror head when the user input is actuated.

Optionally, an exterior rearview mirror assembly of the present invention may include a turn signal indicator or the like for indicating to drivers of other vehicles that the driver of the equipped vehicle has actuated a turn signal of the vehicle. The turn signal indicator of the exterior rearview mirror assembly may utilize aspects of the mirror systems described in U.S. Pat. Nos. 6,198,409; 5,929,786 and 5,786,772, and/or International Publication Nos. WO 2007/005942 and/or WO 2008/051910, which are hereby incorporated herein by reference in their entireties. The signal indicator or indication module may include or utilize aspects of various light modules or systems or devices, such as the types described in U.S. Pat. Nos. 7,581,859; 6,227,689; 6,582,109; 5,371,659; 5,497,306; 5,669,699; 5,823,654; 6,176,602 and/or 6,276,821, and/or U.S. patent application Ser. No. 13/891,619, filed May 10, 2013 and published Sep. 19, 2013 as U.S. Publication No. US-2013-0242586, and/or Ser. No. 13/249,433, filed Sep. 30, 2011, now U.S. Pat. No. 8,764,256, and/or International Publication No. WO 2006/124682, and/or U.S. provisional applications, Ser. No. 61/970,582, filed Mar. 26, 2014, Ser. No. 61/939,766, filed Feb. 14, 2014, and Ser. No. 61/937,138, filed Feb. 7, 2014, which are hereby incorporated herein by reference in their entireties.

For example, and with reference to FIGS. 12-15, the exterior rearview mirror assembly 110 may include a projection turn signal indicator 112 that projects a turn signal icon or arrow onto the ground at or near the side of the vehicle at which the mirror assembly is mounted. The projection signaling of the present invention uses a projection logo light module with a colored illumination source (such as a colored light emitting diode (LED), such as an amber colored LED or the like) in conjunction with the vehicle's turn signal to display an arrow (or other suitable icon or symbol) on the ground adjacent to vehicle. The turn signal indicator or module thus may produce a large blinking symbol at the ground, which may enhance visibility of the turn signal indication to vehicles, cyclists, and pedestrians who may be located in the blind spot of the signaling or equipped vehicle. The mirror assembly may also include a turn signal indicator and/or spot light and/or multifunction lighting module 114 (FIG. 15), such as by utilizing aspects of the mirror systems described in U.S. patent application Ser. No. 13/891,619, filed May 10, 2013 and published Sep. 19, 2013 as U.S. Publication No. US-2013-0242586, and/or Ser. No. 13/249,433, filed Sep. 30, 2011, now U.S. Pat. No. 8,764,256, and/or U.S. provisional applications, Ser. No. 61/970,582, filed Mar. 26, 2014, Ser. No. 61/939,766, filed Feb. 14, 2014, and Ser. No. 61/937,138, filed Feb. 7, 2014, which are hereby incorporated herein by reference in their entireties, and the light module may operate in tandem with the projection light.

The projection icon or logo light module can also be used in conjunction with brake lights, hazards, reverse lights, or other vehicle indicator systems to increase signal visibility. Optionally, the symbol or icon that is projected onto the ground may be adjusted depending on the input. For example, a red stop indication may be projected onto the ground when the brake lights of the vehicle are actuated.

Optionally, the mirror assembly may include a turn signal indicator module, which may also provide a blind zone indicator function. For example, and with reference to FIGS. 16-20, a turn signal indicator and blind zone indicator module 114′ may be disposed at an exterior rearview mirror assembly 110′. The module 114′ includes a turn signal indicator portion 120′, which is operable to emit a turn signal indication 120 a′, and a blind zone indicator portion 122′, which is operable to emit a blind zone indication 122 a′, with both indications being viewable at a rear portion of the mirror assembly, such as shown in FIG. 16. The turn signal indicator portion 120′ and the blind zone indicator portion 122′ are part of a single module 114′. Typically, an exterior mirror that is equipped with a turn signal (TS) and blind zone indicator (BZI) contains two separate modules. The TS/BZI combined module incorporates both functions into one module, utilizing only one printed circuit board (PCB) 124′ and a single cover 126′ that is disposed at or attached at a casing or enclosure 128′ (FIG. 17). Thus, the module minimizes the amount of components, connectors and assembly processes.

The TS/BZI combined module 114′ uses light guides, and uses a single light source location that is not visible from outside the mirror, with the light guide directing or guiding the light to its intended viewing area. With turn signal indicators, much of the light is directed towards an exit at the outboard end of the module, but there is also a feature along the length of the exposed light guide 120 b′ that scatters the light outward (so as to be viewable from in front of the mirror assembly and vehicle and at the side of the mirror assembly and vehicle). Such a light guide 120 b′ may make the whole light guide emit light uniformly from an outward appearance.

The TS portion 120′ of the TS/BZI combined module 114′ may comprise any suitable light guide turn signal design, with a length of visible light guide 120 b′ and an exit 120 a′ at the outboard rearward end of the mirror. The BZI portion 122′ of the TS/BZI combined module 114′ has a light guide that, unlike the TS light guide, may remain hidden behind the mirror housing 110 a′. Instead of exiting at the outboard side of the mirror, the BZI light guide end 122 a′ is disposed at and/or protrudes through the mirror bezel (or emits light through a window at the mirror bezel or casing or reflective element 111′), aimed at least partially towards the driver. This causes the BZI symbol to appear next to the mirror glass in the driver's view, such as shown in FIG. 16. The BZI symbol can have custom shapes or logos by either changing the cross section of the BZI light guide protrusion, or by using a mask at the end of the protrusion, or any other suitable means.

The TS and BZI light sources 120 c′, 122 c′ are disposed at or on the same PCB 124′ (FIG. 17), but are able to be operated independently. Different color lights or filters can be used to help differentiate between the two emitted lights, as they may both be visible to the driver of the vehicle.

As shown in FIG. 17, the two light guides 120 b′, 122 b′ may be combined in a single cover or lens 126′ (such as a transparent cover or lens) to minimize assembly processes. The module housing or casing 128′ may have a rib 128 a′ between the two light guide portions to limit or minimize or substantially preclude light leaking from one light guide or function into the other. As shown in FIG. 20, when the module 114′ is disposed at an exterior rearview mirror assembly 110′, the TS light guide portion 120 b′ protrudes through and/or is visible at the mirror casing 110 a′, while the BZI light guide portion 122 b′ is disposed behind and is hidden by the mirror casing 110 a′. Thus, light emitted by the light source 120 c′ of the TS indicator portion 120′ may be viewable along the light guide portion 120 b′ and at the end 120 a′ of the light guide portion 120 b′, while light emitted by the light source 122 c′ of the BZI indicator portion 122′ may be viewable only at the end 122 a′ of the light guide portion 122 b′, such as at the inner surface of the mirror casing 110 a′ or at the reflective element 111′ or the like, depending on the particular application of the light module 114′.

Optionally, an exterior rearview mirror assembly may include an imaging sensor (such as a sideward and/or rearward facing imaging sensor or camera that has a sideward/rearward field of view at the side of the vehicle at which the exterior mirror assembly is mounted) that may be part of or may provide an image output for a vehicle vision system, such as a lane departure warning system or object detection system or blind zone alert system or surround view vision system other vehicle vision system or the like, and may utilize aspects of various imaging sensors or imaging array sensors or cameras or the like. Optionally, the camera may be adjustably mounted at the mirror assembly and may extend and retract relative to the mirror head to provide an adjustable and enhanced rearward field of view of the camera. For example, and with reference to FIGS. 21-27, an exterior rearview mirror assembly 210 includes a mirror reflective element 212 received in and/or supported at or by a mirror shell or casing or head portion 214, which is attached at a mounting arm or base 216 at the side of the vehicle. A camera module 220 is disposed at the mirror casing 214 and is adjustably disposed thereat and is adjustable between a retracted position (FIGS. 21, 23 and 25) and an extended position (FIGS. 22, 24, 26 and 27).

The camera mirror assembly of the present invention provides reduced wind drag and limits the need for fold-away mirrors on a vehicle. Optionally, and desirably, the camera mirror assembly of the present invention may be utilized on a type of vehicle that would be used for towing a trailer. Special towing mirrors are usually needed for such cases because the trailer is often wider than the towing vehicle and the driver needs to be able to see around the trailer.

In order to provide the required field of view around a trailer that is towed by the vehicle, the camera may have an alternate mounting position that brings the camera lens outside the width of the trailer. This may be accomplished by an interchangeable camera mount, or by providing an extendable or telescoping mount or arm 222 in the mirror housing that allows for movement of the camera to a trailer towing position (FIGS. 22, 24, 26 and 27).

In the case of an interchangeable camera mount, the camera may be mounted in a normal driving position on the mirror housing when the vehicle is not towing a trailer. To prepare the vehicle for towing, the camera can be re-mounted on the mirror housing using an alternative camera mounting apparatus, or a separate camera with such an extended mounting apparatus may be substituted for the standard camera.

In applications where sufficient space is available in the design, a camera extension mechanism 224 (FIG. 27) may be employed that allows the camera to be moved from the normal inboard position to the towing position without changing the mounting apparatus. The camera movement may be accomplished manually, or may be powered by a motor and drive mechanism. Such a mechanism may be similar to that used to extend known towing mirrors. However, because the camera is smaller and lighter than a typical towing mirror, the extension mechanism can be potentially be made lighter and cost less.

The extension mechanism may comprise any suitable means for moving the camera between the retracted state (where the outer surface of the camera module may generally correspond with the outer surface of the mirror casing around where the camera is disposed) and the extended state. For example, the extension mechanism may comprise a telescoping arm or a rack and pinion extension mechanism or the like, such as by utilizing aspects of the systems described in U.S. Pat. Nos. 7,370,983 and/or 6,690,268, and/or U.S. Publication No. US-2006-0050018, which are hereby incorporated herein by reference in their entireties.

The camera may be extended and retracted responsive to a user input (such as a button or the like disposed in the vehicle) that is actuatable by the driver of the vehicle when the driver is normally operating the vehicle. For example, when the driver needs or wants to see further around the towed trailer (or other object or obstacle at or near the rear of the vehicle), the driver can actuate the user input, whereby the camera will extend laterally outwards from the mirror head and whereby a display in the vehicle will display video images captured by the camera for viewing by the driver of the vehicle while normally operating the vehicle.

When the camera is retracted (such as when the vehicle is parked or turned off or responsive to the user input or other user input or the like), the display may continue to display images captured by the camera. Optionally, the display will no longer display the captured images captured by the mirror camera when the camera is retracted.

Optionally, the camera may rotate about the longitudinal axis of the extension arm to provide an enhanced downward field of view of the camera, such as for use in bird's-eye view or surround view vision systems or the like, such as of the types discussed below. The extension and/or pivoting may be done responsive to a user input or responsive to the bird's-eye view display system operating, such as when the driver shifts the vehicle into reverse gear.

Optionally, an exterior rearview mirror assembly of the present invention may include a spotter mirror element to provide a wide angle rearward field of view to the driver of the vehicle equipped with the mirror assembly. The spotter mirror element may utilize aspects of the mirrors described in U.S. Pat. Nos. 7,255,451; 7,195,381; 6,717,712; 7,126,456; 6,315,419; 7,097,312; 6,522,451; 6,315,419; 5,080,492; 5,050,977; 5,033,835; 8,021,005; 7,934,844; 7,887,204; 7,824,045 and 7,748,856, which are hereby incorporated herein by reference in their entireties.

Optionally, the spotter mirror may comprise a mirror element that is separate from the principal mirror reflective element, and the spotter mirror may be fixedly disposed relative to the mirror casing. For example, and with reference to FIGS. 28-30C, an exterior rearview mirror assembly 310 includes a mirror reflective element 312 adjustably received in and/or supported at or by a mirror shell or casing or head portion 314, which is attached at a mounting arm or base at the side of the vehicle. A spotter mirror cap element or skull cap spotter 316 includes a mirror casing portion 316 a and a spotter mirror element portion 316 b. The mirror casing portion 316 a is configured to attach at the mirror assembly and may replace a typical or known mirror casing portion. When so attached, the spotter mirror element portion 316 b is disposed at a corner region of the reflective element 312, which may have its corner region cut away or removed to provide clearance for the spotter element 316 b when the reflective element 312 is adjusted relative to the mirror casing (such as via a mirror actuator in the mirror casing).

The skull cap spotter element of the present invention thus removes the separate glass spotter from the reflective element and incorporates a spotter element into a one-piece skull cap/spotter combination. The cap and spotter may comprise an integrally formed or molded plastic element, and may be coated with a reflective coating, such as a chrome coating or the like. The skull cap plastic spotter thus is a single piece of chromed plastic that combines the chrome skull cap of the mirror housing with a chromed plastic spotter. The combined skull cap and spotter unit provides a chrome accent on the front of the housing of the mirror, as well as a view of the vehicle's blind spot from the rear facing side of the mirror assembly. The skull cap plastic spotter may be integrated into the mirror assembly by fitting underneath, over, or by replacing the upper, outer corner of the bezel. The mirror assembly may be modified to allow assembly of the skull cap plastic spotter by removing the glass spotter (if the mirror has one) and optionally removing or not including the corner section of the mirror reflective element that may typically support a glass spotter element.

Optionally, the exterior mirror element of a mirror assembly may include heater pad or film or element at a rear surface of the mirror reflective element. The heater pad or element at the rear surface of the glass substrate may comprise a mirror defrost/demisting heater and may provide an anti-fogging of de-fogging feature to the exterior mirror assembly, and may utilize aspects of the heater elements or pads described in U.S. Pat. Nos. 8,058,977; 7,400,435; 5,808,777; 5,610,756 and/or 5,446,576, and/or U.S. patent application Ser. No. 11/779,047, filed Jul. 17, 2007, and published Jan. 17, 2008 as U.S. Pat. Publication No. 20080011733; and/or Ser. No. 13/111,407, filed May 19, 2011 and published Nov. 24, 2011 as U.S. Publication No. US-2011-0286096, which are hereby incorporated herein by reference in their entireties. The heater element may include electrical contacts that extend rearward therefrom and through an aperture of attaching portion of back plate for electrical connection to a wire harness or connector of the mirror assembly, or the back plate and/or heater pad may include suitable electrical connectors and connections incorporated therein (such as by utilizing aspects of the mirror assembly described in U.S. Pat. No. 7,400,435, which is hereby incorporated herein by reference in its entirety) for electrically connecting the heater pad (or other suitable electrical connectors may be utilized, such as electrical leads or wire harnesses or pigtails or other separate connectors or cables or the like). Optionally, the heater pad may comprise a screen printed heater pad. For example, the heater pad can be printed on the back of the mirror reflective element (such as at the fourth or rear surface of the rear substrate). Such coatings may be printed and then cured at around 120 degrees C. or lower, making this process compatible with already formed laminate type EC mirror elements, such as those described in U.S. Pat. No. 5,724,187, which is hereby incorporated herein by reference in its entirety. This would make it compatible with EC mirrors.

Optionally, the mirror assembly may include a blind spot indicator and/or a turn signal indicator, such as an indicator or indicators of the types described in U.S. Pat. Nos. 6,198,409; 5,929,786 and 5,786,772, and/or International Publication Nos. WO 2007/005942 and/or WO 2008/051910, which are hereby incorporated herein by reference in their entireties. The signal indicator or indication module may include or utilize aspects of various light modules or systems or devices, such as the types described in U.S. Pat. Nos. 7,581,859; 6,227,689; 6,582,109; 5,371,659; 5,497,306; 5,669,699; 5,823,654; 6,176,602 and/or 6,276,821, and/or International Publication No. WO 2006/124682, which are hereby incorporated herein by reference in their entireties.

Such an indicator or indicators may function as a lane change assist (LCA) indicator or indicators and/or a blind spot indicator or indicators. Such blind spot indicators are typically activated when an object is detected (via a side object or blind spot detection system or the like such as described in U.S. Pat. Nos. 7,038,577; 6,882,287; 6,198,409; 5,929,786; 5,786,772 and/or 7,720,580; and/or International Publication No. WO 2007/005942, which are hereby incorporated herein by reference in their entireties) at the side and/or rear of the vehicle (at the blind spot) and when the turn signal is also activated, so as to provide an alert to the driver of the host vehicle that there is an object or vehicle in the lane next to the host vehicle at a time when the driver of the host vehicle intends to move over into the adjacent lane. Optionally, and alternately, the indicator or indicators may function as a lane change assist indicator or indicators, where the host vehicle may be detected to be moving into an adjacent lane without the turn signal being activated, and an object or vehicle may be detected at the adjacent lane, whereby the LCA indicator or indicators may be activated to provide an alert to the driver of the lane change to assist the driver in avoiding unintentional lane changes and/or lane changes when a vehicle or object is detected in the adjacent lane.

The blind spot indicators thus may be operable to provide an indication to the driver of the host vehicle that an object or other vehicle has been detected in the lane or area adjacent to the side of the host vehicle. The blind spot indicator may be operable in association with a blind spot detection system, which may include an imaging sensor or sensors, or an ultrasonic sensor or sensors, or a sonar sensor or sensors or the like. For example, the blind spot detection system may utilize aspects of the blind spot detection and/or imaging systems described in U.S. Pat. Nos. 7,038,577; 6,882,287; 6,198,409; 5,929,786; 5,786,772; 7,881,496 and/or 7,720,580, and/or of the reverse or backup aid systems, such as the rearwardly directed vehicle vision systems described in U.S. Pat. Nos. 5,550,677; 5,760,962; 5,670,935; 6,201,642; 6,396,397; 6,498,620; 6,717,610 6,757,109 and/or 7,005,974, and/or of the automatic headlamp controls described in U.S. Pat. Nos. 5,796,094; 5,715,093 and/or 7,526,103, and/or of the rain sensors described in U.S. Pat. Nos. 6,250,148 and 6,341,523, and/or of other imaging systems, such as the types described in U.S. Pat. Nos. 6,353,392 and 6,313,454, which may utilize various imaging sensors or imaging array sensors or cameras or the like, such as a CMOS imaging array sensor, a CCD sensor or other sensors or the like, such as the types disclosed in commonly assigned, U.S. Pat. Nos. 5,550,677; 5,760,962; 6,097,023 and/or 5,796,094, and/or PCT Application No. PCT/US2003/036177 filed Nov. 14, 2003, published Jun. 3, 2004 as PCT Publication No. WO 2004/047421, with all of the above referenced U.S. patents, patent applications and provisional applications and PCT applications being commonly assigned and being hereby incorporated herein by reference in their entireties.

The reflective element of the rearview mirror assembly of vehicles may include an auxiliary wide angle or spotter mirror portion, such as the types described in U.S. Pat. Nos. 7,255,451; 7,195,381; 6,717,712; 7,126,456; 6,315,419; 7,097,312; 6,522,451; 6,315,419; 5,080,492; 5,050,977 and/or 5,033,835, which are hereby incorporated herein by reference in their entireties, and optionally may have an integrally formed auxiliary mirror reflector, such as the types described in U.S. Pat. Nos. 8,736,940; 8,021,005; 7,934,844; 7,887,204; 7,824,045 and 7,748,856, which are hereby incorporated herein by reference in their entireties. The auxiliary wide angle optic may be integrally formed such as by physically removing, such as by grinding or ablation or the like, a portion of the second surface of the front substrate so as to create or establish a physical dish-shaped generally convex-shaped depression or recess or crater at the second surface of the front substrate, and coating the formed depression or recess with a reflector coating or element or the like, such as described in U.S. Pat. No. 8,021,005, incorporated above. The mirror reflective element includes a demarcating layer or band or element that is disposed or established around the perimeter of the reflective element and around the perimeter of the spotter mirror so as to demarcate the spotter mirror from the main reflector portion to enhance the viewability and discernibility of the spotter mirror to the driver of the vehicle, such as by utilizing aspects of the hiding layers described in U.S. Pat. No. 8,736,940, which is hereby incorporated herein by reference in its entirety. The demarcating layer or contrasting coating or layer or material may comprise any suitable material, and may provide a different color or reflectivity or may comprise a dark or opaque color to demarcate the spotter mirror and enhance discernibility of the spotter mirror from the main mirror, which may comprise a flat mirror, a convex mirror or a free form mirror (such as utilizing aspects of the mirrors described in U.S. patent application Ser. No. 13/942,751, filed Jul. 16, 2013, now U.S. Pat. No. 8,917,437, which is hereby incorporated herein by reference in its entirety).

The mirror assembly may comprise any suitable construction, such as, for example, a mirror assembly with the reflective element being nested in the mirror casing and with the mirror casing having a curved or beveled perimeter edge around the reflective element and with no overlap onto the front surface of the reflective element (such as by utilizing aspects of the mirror assemblies described in U.S. Pat. Nos. 7,255,451; 7,289,037; 7,360,932; 8,049,640; 8,277,059 and/or 8,529,108, or such as a mirror assembly having a rear substrate of an electro-optic or electrochromic reflective element nested in the mirror casing, and with the front substrate having curved or beveled perimeter edges, or such as a mirror assembly having a prismatic reflective element that is disposed at an outer perimeter edge of the mirror casing and with the prismatic substrate having curved or beveled perimeter edges, such as described in U.S. Des. Pat. Nos. D633,423; D633,019; D638,761 and/or D647,017, and/or International Publication Nos. WO 2010/124064, WO 2011/044312, WO 2012/051500, WO 2013/071070 and/or WO 2013/126719, which are hereby incorporated herein by reference in their entireties (and with electrochromic and prismatic mirrors of such construction are commercially available from the assignee of this application under the trade name INFINITY™ mirror).

Optionally, aspects of the mirror assemblies described above may be suitable for use in an interior rearview mirror assembly. Optionally, an interior rearview mirror assembly of the present invention may include a user input or button that is at or aligned with or at least partially protruding through a hole in the glass substrate or substrates of the mirror reflective element. For example, and with reference to FIGS. 37-41, an interior rearview mirror assembly 410 for a vehicle includes a casing 412 and a reflective element 414 positioned at a front portion of the casing 412, and the mirror assembly is configured to be adjustably mounted to an interior portion of a vehicle (such as to an interior or in-cabin surface of a vehicle windshield or a headliner of a vehicle or the like) via a mounting structure or mounting configuration or assembly 416. In the illustrated embodiment, a user input or button 418 is established at a hole or aperture 414 a through the reflective element 414. The user input 418 is disposed at or connected with circuitry 420 of a circuit element 422 within the mirror assembly (FIG. 27), and may be associated with one or more illumination sources or light emitting diodes (LEDs) 424 or the like.

Typically, a user input for an interior rearview mirror assembly is located at the bezel of the mirror assembly, either at the front face of the mirror assembly or protruding from the lower surface of the mirror casing or housing. It is also known to provide capacitive switches behind the glass reflective element to limit or preclude the need for a bezel in cases where a mirror has a forward facing switch or input. The present invention provides a tactile button or switch element that protrudes through a hole in the glass mirror reflective element. Similar to capacitive switches, no bezel is needed to house the user input.

Optionally, and desirably, the user input system of the present invention includes an illumination source that, when activated, may backlight an icon at the surface of the button. The light source, when activated, may produce a soft glow around the perimeter of the button that is visible in the glass surrounding the button and hole. Optionally, and as can be seen in FIGS. 32-34, the outer or front glass surface of the glass substrate of the reflective element 414 may be chamfered or tapered at and around the hole 414 a to further enhance the glow effect at and around the user input or button. For applications of the user input on frameless mirror elements (with the perimeter edge being rounded or curved and exposed), the light source has the added benefit of piping through the glass element (either a prismatic glass element or a front glass substrate of an electrochromic reflective element) and expanding outwards to the exposed perimeter edge of the glass substrate. When the perimeter edge is polished as in the INFINITY™ mirror designs, the perimeter edge will glow when the light is activated, thereby creating a theater effect.

Optionally, a mirror assembly of the present invention, such as an interior or exterior rearview mirror assembly, may include one or more electrically powered accessories or elements or devices. For example, a passenger vehicle exterior rearview mirror may have many electrical features such as motorized mirror adjustment actuators with position sensors, heaters, motorized retract feature, self-darkening glass, turn indicators, blind zone alert indicators, ground illuminators and/or the like. Each of these accessories or devices has wires connected to it that are routed from the rear-view mirror assembly into the door or body of the vehicle.

In such a full-featured exterior rearview mirror, and such as can be seen with reference to FIG. 36, the wire harness may have up to about twenty wires or more leading from the mirror assembly into the vehicle. This causes difficulty with harness routing and connection reliability, and adds a significant amount of cost and weight to the vehicle.

As shown in FIG. 36, various wired connections may be made within a vehicle to control the mirror functions. Wiring for individual functions are shown in FIG. 36 at the driver side mirror, while all functions are shown grouped together on the passenger side mirror for simplicity. Some vehicles may also incorporate a door control module in the passenger door which has been omitted for simplicity.

Optionally, in order to reduce the number of wires at the mirror assembly, the mirror assembly may use wireless communication technology. As wireless technology becomes more common in the marketplace, wireless hardware costs are decreasing to the point where wireless technology will eventually become a viable alternative to wires for many functions in a vehicle.

If power from the vehicle bus is supplied to the mirrors, all other function control can be accomplished using wireless technology, such as Bluetooth 4.0 (BLE) or Zigbee or the like. RFID technology can additionally be used in the case of switches, which could further eliminate the need to route power wires to the switch module. For example, and as shown in FIG. 37, the mirror may use wireless technology to provide control of the various accessories or electrical content and/or features, such as sensors and actuators of the types described above and/or such as other accessories, including illumination sources or modules (such as for ground illumination, blind zone indication, turn signal indication and/or the like), heating elements, cameras and/or the like.

The reflective elements of the mirror assemblies described above may comprise an electro-optic or electrochromic mirror assembly that includes an electro-optic or electrochromic reflective element. The perimeter edges of the reflective element may be encased or encompassed by the perimeter element or portion of the bezel portion to conceal and contain and envelop the perimeter edges of the substrates and the perimeter seal disposed therebetween. The electrochromic mirror element of the electrochromic mirror assembly may utilize the principles disclosed in commonly assigned U.S. Pat. Nos. 7,274,501; 7,255,451; 7,195,381; 7,184,190; 6,690,268; 5,140,455; 5,151,816; 6,178,034; 6,154,306; 6,002,544; 5,567,360; 5,525,264; 5,610,756; 5,406,414; 5,253,109; 5,076,673; 5,073,012; 5,117,346; 5,724,187; 5,668,663; 5,910,854; 5,142,407 and/or 4,712,879, and/or International Publication No. WO 2010/114825, which are hereby incorporated herein by reference in their entireties, and/or as disclosed in the following publications: N.
